CHAIR-SLEEPER FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 433,875, dated August5, 1890.

Application filed M 7. 1890. Serial No. 350,920. (No model.) Patented inEngland July 2, 1889, No. 10,702, and January 8, i

To all whom it may concern;

Be it known that I, WYBRAN'rs GEORGE OLPHERTS, a citizen of England,residing at 38 Ebury Street, Pimlico, in the county of London, England,have invented a certain new and useful Improvement in Chair-Sleepers forRailways, (for which I have obtained patents in England, dated July 2,1889, No. 10,702, and dated January 8, 1890, No. 354,) of which thefollowing is a specification.

My invention relates to the construction of chair-sleepers for railways,such that with comparatively little weight of metal I obtain greatstrength and firmness of fixing in the ballast, convenient and readymeans for securing the cross-ties with accuracy of gage, and a fixing ofthe rail without the use of wooden keys, which are liable to looseningand decay.

My invention is applicable either to doubleheaded or to flanged rails,as I shall describe, referring tothe accompanying drawings.

Figure 1 is a side view, Fig.1 2 is a plan, Fig. 3 is an end view, Fig.4 is a section on the line Z Z of Fig. 2, and Fig. 5 is a plan lookingfrom below, of a chair-sleeper, according to my invention, suitable fordouble headed rails. Fig. 6 is a side view of the tiebar. Fig. 1. is aside View, Fig. 2 is a plan, and Fig. 3 is an end'view, of thechair-sleeper somewhat modified to hold a flanged rail; and Figs. 4 and5 are respectively a back view and a side view of the movable jaw.

Referring, first, to Figs. 1 to 6, inclusive, the base A of the sleeperis of rectangular form with rounded ends, having a downwardlyprojectinglip B all around its edge and a cen tral rib O projecting down into theballast, supported on each side by two cross-ribs D. One of the jaws E,which hold the r ail,is cast in one piece with the sleeper. The otherjaw F isfitted to slide between two side ribs G, which project up fromthe sleeper, and is secured in position by a Wedge-key H, preferably ofsteel, which is driven through slots of the ribs G' and through a grooveof the jaw F.

At the one side of the central rib C slots are formed through thecross-ribs D, and the tie-bar K is made with notches 7c in its underedge in such positions that when the tiebar is slid through the slots ofD it can be lowered the depth of its notches k, and thus held securelyin position. In order to prevent it from rising so as to disengage itsnotches k, a tongue f, projecting down from the other suiting the gagefor curves, so thatv by inverting the tie-bar it can be usedlundereither condition. The jaws E and F are made with faces somewhat inclinedto give the'rail its desired tilt. They also support it under the head,so that the lower face of the rail is not deformed by hammering on thesleeper below, and consequently the rail can be inverted when required.

In Figs. 1, 2, and 3 the parts corresponding with those in Figs. 1, 2,and 3 are marked with similar letters of reference, the only differencein the two chair-sleepers being that the jaws E and F are so shaped asto clip the flange of the rail instead of clamping its body.

Having thus describedthe nature of my invention and the best means Iknow of carrying the same into practical effect, I claim A chair-sleeperfor railways, consisting of a bearing-plate longitudinally andtransversely ribbed and lipped at the edge, having integral with it onefixed jaw and two upwardly-projecting ribs, in combination with amovable jaw secured between the said ribs by a Wedge-key, and a tie-barhaving notches engaged on the transverse ribs, substantially asdescribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 24th day of April, A. D.1890.
